SDU

SDU - Subsea Distribution Unit The SDU is located subsea and provides the hydraulic, chemical and electrical distribution between the SUTA (Subsea Umbilical Termination Assembly) and the rest of the subsea system. The SDU distributes the hydraulic, chemical and electrical supplies to the flying leads which in turn connect to the subsea trees and subsea manifolds. The SDU is mounted onto a special mounting base which in turn is installed onto a subsea foundation such as a mudmat.(click on photo to enlarge)
